GAF185 ... GAF300 3-pole contactors

250 to 400 A DC-1
AC / DC operated with 1 N.O. + 1 N.C. auxiliary contact

Description
GAF185 ... GAF300 contactors are designed for controlling resistive or slightly inductive loads up to 1000 V DC.
These contactors are of the block type design with 3 main poles for connection in series by the user accord-
ing to conductor cross-sectional area or by using LP connection bars to be ordered separately.
– main poles arc chutes fitted with permanent magnets specially designed for DC breaking. The connection
1SFC101098F0001 – control circuit: AC or DC operated with electronic coil interface accepting a wide control voltage range
polarities must be respected.
(e.g. 100...250 V AC and DC), only 3 coils to cover control voltages between 48...250 V 50/60 Hz and
20...250 V DC
GAF185-10-11 - can manage large control voltage variations
- reduced panel energy consumption
- very distinct closing and opening
- can withstand short voltage dips and voltage sags (SEMI F47 conditions of use on request).
– built-in surge suppression
– add-on auxiliary contact blocks for side mounting and a wide range of accessories.
